I will second the Craftmates but use a little different product: I have 4 of the 14 compartment boxes:

What I like about these is that each box has an individual compartment for each hook that locks individually as well. If you drop it, only one size goes all over the floor. Can you tell that I had a different hook box in the past and dumped it? What a gigantic mess and sorting hooks was an adventure, the likes of I don't want to revisit.
The other pleasing thing to me about this method is that all of these boxes fit nicely my Fishpond Coyote bag so when it is time for a class I put them in and go. Some of the larger base station type of boxes are nice but if you go to shows or classes, I much prefer these.
